Looks like KBin has an edge over Lemmy now in terms of monthly active users.
It's obviously a pretty silly thing, and is not in any way indicative of which project is "better" or more "long-term viable" or anything — instances of both federate with one another, and with the rest of fedi, so it's all one happy family.
That said, it's notable. KBin is a relative newcomer to the "Reddit-like fedi instance" game, and also does not have the tankie baggage.
Anyway, the more, the merrier!

A lot of people seem to be talking about whether PHP has enough developer support, but that isn't the main issue.
The issue is that code written in PHP is probably at least 10 times less efficient in terms of CPU and memory than the equivalent code written in Rust.
This means that loads of hobbyist developers will be able to run lemmy instances for a fraction of the ongoing cost of kbin.
